EVE 35V 6S 18650 Battery Pack 22.2V (25.2V Full Charge) 3500mAh with Protection Board – 8A Pre-wired DC Female & XH2.54 Connector for 24V DIY Electronics
Description
High-voltage, high-capacity power for your custom 24V projects.
This EVE 35V 6S 18650 Battery Pack is assembled from six genuine EVE 18650-35V cells in a 6S1P (series) configuration. It delivers a high nominal voltage of 22.2V (25.2V full charge) and a solid 3500mAh capacity.
Designed for advanced DIYers and custom electronic builds, it features a built-in Protection Board (BMS) that safeguards against overcharge, over-discharge, and short circuits. The continuous discharge current is limited to 8A (with a 20A instantaneous peak), making it ideal for medium-power devices rather than heavy-duty power tools.
It comes pre-wired with a DC Female connector for main power output and a XH2.54-2P connector for charging or balancing, ready to integrate into your 24V systems. (Note: The image shows a DC female plug, please verify the plug size matches your device).
Key Features
6S Configuration (22.2V / 25.2V): Delivers high voltage for devices that require a 24V power source.
Genuine EVE 35V Cells: Authentic, high-quality cells provide reliable capacity, low internal resistance, and long cycle life.
Built-in Protection Board (BMS): Features overcharge, over-discharge, and short-circuit protection. Limits continuous output to a safe 8A.
Dual Connector Setup: Includes a DC female plug for power delivery and an XH2.54-2P connector for charging.
Compact Linear Layout: Shrink-wrapped in a 6-cell row (approx. 112mm x 73mm x 19mm), designed to fit compact enclosures.

Applications
Recommended For:
24V LED Lighting: Ideal for high-power LED strips, work lights, and custom lighting systems (under 8A load).
DIY Electronics: Custom 24V power supplies for amplifiers, sensors, and portable devices.
Robotics & Automation: Reliable 22.2V power for robot controllers and motors (drawing <8A).
Portable Power Stations: Build your own 24V backup power bank.
Not Recommended For:
High-Drain Power Tools or RC Models: Do not use in drills, saws, RC cars, or drones. The 8A BMS limit will trip under heavy loads.
Devices Requiring Bare Cells: This pack cannot fit in standard spring-contact battery compartments.
12V Devices: The 22.2V/25.2V output will instantly damage 12V equipment.
FAQ
Q1: What does "6S" mean and what is the actual voltage?
A: "6S" means 6 cells in Series. The nominal voltage is 22.2V, and it charges up to a maximum of 25.2V. Ensure your device can handle this voltage range.
Q2: What is the maximum discharge current?
A: The built-in protection board limits the continuous working current to 8A. The peak instantaneous current is 20A. It is not designed for continuous high-drain use.
Q3: How do I charge this pack?
A: You must use a dedicated 6S Li-ion charger (25.2V output). You can connect it via the XH2.54-2P connector (typically red to positive, black to negative) or through the main DC port if your charger supports it.
Q4: Can I use this for my power tool?
A: No. Power tools generally require 20A to 40A continuous. The 8A limit will cause the BMS to cut power immediately under load.
Q5: What is the DC female connector size?
A: It is a standard DC barrel jack (commonly 5.5mm outer diameter / 2.1mm or 2.5mm inner pin). Please verify the exact size against your device's male plug before ordering.
Payment & Security
Your payment information is processed securely. We do not store credit card details nor have access to your credit card information.
Drained it accidentally and the board protected the cells. Recharged normally.
Solid without being a brick. Fine for a project box.
Portable scope and DMM both happy. No noise on the rails.
Needed a firm push to seat the barrel plug, but it clicked in fully. No wobble.
Carries easily and runs my 24V QRP rig for hours on end.
